""lieation led November 13, 1909. Serial No. 527,964.

To all whom it may concern:

lie it known that I, AnoLrIr L. Dn LEEUW,

a eitizenof the' United States, residing at I Ilamilton, in the county of Butler and State ot' Ollio, have invented certain new and useful Improvements in Millingl\lachines, of which the following is a specilieation.

l\'l v invention relates to nu improvement in milling machines` prinnuily to that type known as a universal machine.

The object of my invention is to rovide means in the path of table tra-vel o a universa] milling -..machine, for 'automatically trippin the feeding devices governing the feed ofg the table, together Awith means for manually Controlling the sa1ne.

The features of the invention. are lnore fully set forth in the description of the ac` companying drawings, forming a part of this specification, in which :i-

Figure l is. a side elevation of a universal milling,r machine illustrating the knee and its contained. parts and a portion of the frame. Fig. 2 is a central vertical section through` the klee and its 'contained parts. Fig. '3 is a section on line rc, a', Fig. 2, with the tableshown inelevation. .Fig 4 is a sect-ion on line y, y, Fig. 3. Fig. 5 isa section on line uf, Fig. Fig. 6 isa front elevation of a portion of the table and carriage, illustratingr the clutch tripping mechanism i .in the path of table travel.I

actuatin lever is in the form iss 1 represents the frame of a milling machine, provided with the usual slide-way 2, upon which the knee 3 travels. 4 represents the feed shaft in suitable driving connection with the main power devices, not shown, said shaft 4 being of universal form to.permit the knee vto ybe raised'or lowered upon its slide-way 5, G, represent gears forming driving members for the various feed shafts for the vertical feeding-of the knee and the horizontal feeding of the table. The gears 5, G, are loose noon the shaft 7, and 8 represents a clutch membenadapted tobe alternately engaged With either oneof; the gears 5, 6. for engaging the same infdriving relation with the shaft 7. 9 represents-a clutch actuating lever pivotally mounted for shiftmg the clutch to control `the enga ements of gears 5, 6, with the shaft. aid clutch of a sector, provide with rackl teeth, adapted to engagean elongated pinionflQ, carried by the stud shaft 11, suitably-supported: in the gear -32 represents a beveled main frame 1', for automatically controlling the vertical feed of the knee 3. -16 represents a rod slidably mounted in the housin frame 17, provided with a beveled head 18 and rack teeth intermeshed with the pinion 10, for actuatlng the clutch member 9. Said beveled head is in the' path of travel of the dogs 19,- 20, adjustablv mounted upon the saddle 21, horizontally movable upon the knee 3. These features for automatically controlling or tripping the feed for the knee and saddleare substantially the same as illustrated in a. prior'applioation 'led by me and S. Einstein, jointly, October 23, '1907, Serial No. 398,720, but in which application the feed controlling mechanism was applied to arplain milling lnaeh'ine.

22 represents the carriage swiveled upon the saddle .21, for universally swinging the' carriage and table relative to the cutting tool of the machine.`

23 representsa table slidable upon the carriage. The knee is fedvertically by' power and hand in any Well-known manner and the means for aecomplishlng said feed are therefore lnot illustrated inthe drawings.

The feed of the ltable upon the carriage is accomplished as -foilowsz-24 represents a shaft suitably journaled inithe knee, vsee Fig. 2. 25 represents a gear in train with either one of the gears', 6, .for producin "a forward or reverse rotation ofthe s aft 24. 26 represents a beveled vgear rovided with 'an elongated sleeve jurnaled 1n thelbracket support 27, de ending from themedial por-y tion of the sa dle 21 andprojec't'ed through l '19o is splined to the 4shaft 24 and slidable there.;v

a slot 28, formed in the knee-B. The gear 26 on and movable 'with the satd1e121'.- 29 re resents a vbeveled gear in mesh with beveledl gear 26, fixed to thestud shaft .30, journaled 1n the bracket 27, and 31 represents a' bevev eled gear xed or formedintegral with-the shaft 30. The shaft 30 iif concentric with' the `Xis of adjustment of the cariagei2f2'.-

the beveled gear .31, provided with a "ria e22, see Fig.4 3, -and splined to the table Ain Fig. .3, and atitbe same time vfree to move l fee screw 33, for horizontally feeding the table 23 upon the carriage. The table is rovided wlth a depending nut, of the usual gorm of construct-ion, engaged with the feed screw 33.

To automatically tri the drive by the travel of the table, the ollowing instrumentalities are employed :-34, 35, represent dogs adjustable in the groove 36, formed on-the front face of the table 23, see 3 and 6. 37 represents a rod slidably mounted in a bearing 38, formed on the oarriage22, prov vided with a beveled head 39 in the path of do travel, adapted to be engaged thereby and actuate the rod 37 in a vdirection dendent u on which of the dogs it engages. he rod is-provided with rack teeth 40, intermeshd with a rack pinion 41, formed onthe rod 42, journaled in the carriage see F' s. 3, 5 and 6, with the opposite end ot the r provided with teeth 43, intermeshed with` thel teeth formed on the sleeve 44, loosely supported uponI a sleeve bearing of the bracket 27, adapted to swivel thereon with: the Swivel ng'- of, the carriaI e 22, to which the sleeve 44 is splined, as i lustrated verticall The opposite end of thc sleeve 44 isprovi ed with rack teeth 45, intermeshed intermeshed with a .rockbar 46; pivotally supported within' the saddle 2,1, by means of pins 47, 48, as

1 illustratedin Fig. 4. This rock bar is of elongated form to accommodate the saddle and its contained parts to be adjusted upon the'lmee with the sleeve 44 malntained in constant connection with the rock bar 46' and moving therewith, while. the opposite sideof the rock bar 46 is provided with ,'-teeth extending the entire length thereof and- .slidably mounted in the knee 3, see Fig. 3,- the opposite end of the rod being likewise 'provided with -teeth intermeshing with the teeth?A of the elongated pinion 10, which, as before described,'is in connection with the clutch actuating lever 9. l`hus,'as the trip bar 37 is moved upward or downward, according towheh of the dogs '35 -iten i which vin ytuin rock-s the rock bar 46, there- 4 by actuat' rod 50, elongated gear 10, an'd the clutch ever 9, to vshift the drive from forward to reverse, or vice versa, or stop the ear'tigge feed. The trip rod 37 may be also shi manuallybv means of the lever 51,' xed to the free end of rod 42, see Fi s. 1, 5 and 6, enablin the feed to be contro led in a universal nll ing machineeither automatically or manually from the lforward position withthe teeth'49 of thc'rod 50,

occup relative to the saddle and in 'any ad- `uste' position the parts occupy upon the nee. v

Having described my invention, I claim 1. Ineamachine of the class described, a

saddle, a carriage swiveled thereon, a table sliding on the carriage, a table driving shaft concentric relative to the swivel, feed mechanism between one end of the shaft and'table, a clutch controlled feed mechanism con-- nected to the other end of said shaft, a longitudinally movable and circumferentially toothed sleeve concentric to the swivel, tripping mechanism having connections between one end of thesleeve and the table and between the other end of the sleeve and the clutch. l

2. In a machine of the class described, a knee, a saddle sliding thereon, a carriage swiveled on the saddle, -a table sliding on the carriage, a clutch controlled primary feeding. mechanism, tributary feeds to said saddle and table, the table feed having: a driving shaft concentric to said' swivel, a

longitudinally movable and circumferentially toothed sleeve concentric to said table shaft, tripping mechanism between the table and support., having connections for moving said sleeve, a longitudinal vplunger in the -knee having connections with the clutch,

and a rock bar having elongated toothed connection with said plunger and the sleeve, whereby the table can be; tripped irrespective ofits position' of longitudinal and swiveled adjustment.

` 3. In a devicel of the class described, a knee, a saddle, feeding mechanism for reciprocating the saddle thereon, a feed control, a

carriage swiveled on the saddle, a table slidable on'the carriage, a trip, and devices on the carriage,

adapted to positively reciprocate the tri by the reciprocation of the table, a mem er concentric with the carriage swivel, and devices connectingsaid concentric member with the trip and with the feed control, sald'concentric member' 'being adapted to be reciprocated so as to automatically reverse the feed irrespective of the swiveled position ofthe table.y
